Keyless start

Slide into the driver's seat of your CTS, step on the brake (or clutch, if your CTS is equipped with a manual transmission) and turn the ignition knob; the engine fires up, and you're ready to take on the road. The transmitter in your pocket or purse (the same one that unlocked the door for you) tells your CTS everything it needs to know to get you on the move, keylessly.
